OD Cost matrix doesn't solve anything

Question

Greetings.

I am currently doing a rather simple excercise with utilising the OD Cost Matrix where I'm supposed to connect the warehouses to the stores. Importing of origins and destinations wasn't an issue.  Homever when attempting to solve it the program shows such message:

No "Destinations" found for "One" in "Origins".
No "Destinations" found for "Two" in "Origins".
No "Destinations" found for "Three" in "Origins".
No "Destinations" found for "Four" in "Origins".
No "Destinations" found for "Five" in "Origins".
ERROR 030212: Solve did not find a solution.
No solution found.
Failed to execute (Solve).

I tried various solutions (some of which were proposed from this forum) but to no avail. What do I need to do in order for this to work?

You should not include the Shops and Warehouses in the network dataset as "Source Feature Classes".  Only roads and things you travel on should be part of the network. Your shops and warehouses should be used as analysis inputs.  You add those to your network analysis layer as input Origins and Destinations.  Then, the network is used to model travel from each origin to each destination.  But the network itself should work with any input data, not just the shops and warehouses.

It sounds like you're experiencing some pretty big challenges here.  If you call Support, they can help guide you through the workflow and answer all your questions as they come up.  They can do a lot more than we can do here in this forum.

By that I meant that when creating new network dataset I included all the layers in "Source Feature Classes" since the Shops and Warehouses points does not show them when importing Destinations and Origins as I want to make a OD Cost Matrix with them. I also tried modifying the network itself by modifying what goes and not goes into "Source Feature Classes"

So you created your own network dataset, and you're not using the one provided by the tutorial?  If so, I suspect that's the problem.  Something in the way you've created your network dataset is probably not working right.

I'm not entirely sure what you mean by "When creating one I ordered it to use all of the layers I have loaded (several ones including roads, buildings, points of interests, shops, and warehouses".  When you create a network dataset, it should include only roads and other lines that can be traveled on.  You should not include buildings or points of interest in the network itself.  If you've done that, and then you also try to use those as inputs to the network analysis, the analysis inputs may locate on features in the network that aren't connected to anything.

Here is a tutorial all about how to create a network dataset: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/how-to-create-a-usable-network-dataset.htm

If you're still having trouble, you will probably need to reach out to Esri Support, and they can walk you through the process or examine the network you've created.
